On Evaluating Quantum Kernel Robustness for Low-Resource Cross-Corpus Audio Deepfake Detection
Lisan Al Amin, Lei Zhang, Vandana P. Janeja
Synthetic speech detection is critical for audio security, but performance can degrade when labeled data are scarce and evaluation conditions differ from training. This study exami…
CASC: Causal Adversarial Subspace Clustering for Multivariate Spatiotemporal Data
Francis Ndikum Nji, Vandana Janeja, Jianwu Wang
Deep subspace clustering plays a critical role in applications involving multivariate spatiotemporal data, such as sea ice monitoring, disease spread analysis, and tracking neuro-d…
Linguistically Augmented Audio Speech Data (LinguAS)
Ashley R. Keaton, Zahra Khanjani, Christine Mallinson +1
Maliciously-created fake speech, including deepfaked and spoofed audio, is proliferating at an alarming rate, and detection models are racing to stay ahead of the curve. Yet, most…
Multi-Speaker Conversational Audio Deepfake: Taxonomy, Dataset and Pilot Study
Alabi Ahmed, Vandana Janeja, Sanjay Purushotham
The rapid advances in text-to-speech (TTS) technologies have made audio deepfakes increasingly realistic and accessible, raising significant security and trust concerns. While exis…
Knowledge-Guided Time-Varying Causal Inference for Arctic Sea Ice Dynamics
Akila Sampath, Vandana Janeja, Jianwu Wang
Quantifying the causal relationship between sea ice thickness and sea surface height (SSH) is essential for understanding the mechanisms driving polar climate dynamics. Conventiona…
Physics-Encoded Inverse Modeling for Arctic Snow Depth Estimation
Akila Sampath, Vandana P. Janeja, Jianwu Wang
Accurate estimation of unobserved quantities in time-varying inverse problems remains challenging when observations are sparse and only indirectly related to the target variable. I…
